摘　　要：目的 :探讨 3种不同复合树脂充填方法修复后牙深洞的临床效果。方法 :15 9例后牙Ⅱ类深洞 ,随机分为3组 :Ⅰ组采用玻璃离子垫底加复合树脂充填技术 ,即“夹心”技术 ;Ⅱ组采用流动树脂垫底加复合树脂充填技术 ;Ⅲ组采用直接复合树脂充填技术 ,在充填后的 1月 ,6月 ,12月采用改良USPHS方法进行临床评价。结果 :边缘密合度、充填体完整性、继发龋 3组之间没有显著性差异 ;而边缘变色则Ⅲ组明显高于Ⅱ组 (P <0 .0 5 ) ;充填后反应Ⅰ组明显高于Ⅱ组 (P <0 .0 5 )。结论 :采用流动树脂垫衬加复合树脂修复后牙深洞可以取得最佳效果。Objective: To evaluate the clinical performance of deep posterior class II composite restorations with 3 different techniques. Methods: 159 class II deep posterior cavities, divided randomly into 3 groups: Group I: 49 cavities, restored with ionomer/hybrid composite sandwich technique; Group II: 56 cavities, restored with flowable/hybrid composite; Group III: 54 cavities, restored with direct hybrid composite resin. Clinical evaluations were performed 1 month, 6 month 12 month after restoration with modified USPHS mothed. Results: There were no statistically significant differences in marginal integrity, anatomical form, recurrent caries among three groups; in marginal discoloration, differences between group II and group III were significant (P<0.05); in postoperative sensitivity, differences between group I and group II were statistically significant (P<0.05). Conclusions: Posterior deep cavities restored with flowable composites and hybrid composites can get superior clinical results.
